FEED MECHANISM FOR MUSIC-BOXES.

SPECIFICATION forming' part 0f Letters Patent NO. 427,097', dated May 6, 1890.

Application filed August 29, 1889. Serial No. 322,345. (No model.)

To all whom, it may concern.-

Be it known that I, EENs'r MALKE, of Connewitz, near Leipsic, in the Kingdom of SaX ony, Germany, have invented an Improved Feed Mechanism for Music-Boxes, of which the following is a specification.

Thislinvention relates to a feed mechanism for music-boxes which is more particularly designed to feed very thin perforated paper over the sound-producing devices. Such paper would be apt to become easily crumpled when fed by frictionrollers- I have devised a feed mechanism which positively draws the paper forward through the instrument.

The invention, briefly stated, consists in a pair of endless belts connected at one point by a cross-bar, which is adapted to hold the forward edge of the paper. Thus the motion of the belts feeds the paper over the reeds or valves that produce the sound.

In the accompanying drawings, Figure l is a vertical longitudinal section of a musicbox having a comb of sounding-teeth and provided with my improved feed mechanism. Fig. 2 is avertical cross-section on lineman, Fig. l. Fig. 3 is a vertical cross-section on line e, Fig. l; Fig. 4L, a face view of the cross-piece Q; Fig. 5, a section on line y y, Fig. 4, showing the catch closed; Fig. 6, a similar section with the catch open. Fig. 7 is a vertical longitudinal section of avalve music-box provided with my invention, and showing the valves closed. Fig. S is a similar section with the valves open.

The letter A represents a music-box of suitable construction and having either combteeth A as in Fig. l, reeds with valves A2, as in Figs. 7 and 8, or other equivalent musicproducing devices which are put into action by a perforated sheet of paper in the well` known manner.

A3 represents the crankshaft of the musicbox, to which power is applied and upon which are rigidly mounted two disks S S, one near each end.

B B are a pair of endless belts or bands passing over thc disks S S and over a series of disks L L, hung loosely upon their shafts A4. Between the disks S S an d between the disks L L rollers M are loosely hung upon their shafts. The bands B B are connected at any suitable point by a cross-bar Q, such cross-bar being provided at its end with perforations p, adapt ed to engage buttons r on belts B. Thus the cross-bar can be readily attached or removed. The cross-bar Q is adapted to firmly engage one edge of the perforated music-sheet N. To this effect it is provided with a catch of any suitable construction.

In use the sheet N is secured to the crosspiece Q, the latter is slipped over buttons fr, and the crank-shaft A3 is turned. rlhe sheet N will be drawn between bands B over the several rollers M by a positive feed, and will thus at all times be kept perfectly taut.

To remove the shcet N, it is only necessary to detach it from the cross-piece Q., when it may be freely drawn out of the music-box.

"What I claim isy I. The combination of a music-box with a pair of endless belts B,and with a cross-piece Q, connecting the belts and provided with a catch for engaging the music-sheet, substantially as specified.

2. The combination of music-box A with a series of shafts carrying disks and rollers, an d with a pair of endless belts B, having buttons fr and passing over the disks, and with a crosspiece Q,having a catch and adapted to be engaged by said buttons,substantially as specitied.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ERNST MALKE.
